AIO? Bf shaves his taint on the couch

My boyfriend has a habit of shaving his balls and taint directly onto the couch. This really grosses me out, but he tells me it’s not a big deal and to get over it.

When he’s done I have to remind him to sweep the hair onto the floor. He doesn’t wipe it down with a wet rag and cleaner or anything.

Am I overreacting?
